Strange output from Epson 3880

I'm printing a color image on Hahnemulle Smooth Surface 308gsm on an Epson 3880. I'm getting this strange break where the color seems to stop and then it is just black. No transition at all. Almost like a varnish on dull paper kind of effect.

I'm using the Hahnemulle profile, and have tried perceptual, relative colorimetric, black point on and off in all the possibilities.
